migration from usage of config() to just an object of config.
no relevant issue
- Change 'loadConfig' task to 'ensureConfig' to more accurately reflect
what it is actually doing. Its sole purpose is to make sure a `config.js`
file exists, and as such the name now reflects that purpose.
- Update config/index.js to export the ghostConfig object directly
so that it can be accessed from other modules
- Update all references of config(). to config.
This was a blind global find all and replace, treat it as such.
- Fixes to tests to support new config access method
- Allow each test to still work when invoked invidually
refs #2600
- fixed issue with defaults not being populated on upgrade
- added logging to all actions in the migration process to help debugging
in future
- did a little bit of refactoring
